OK this is a stupid question, but i just dont know the anwser. I am going to wire up my electric fan to a switch. it will be just strait wires from the batterie to the fan. the question is do i just run a wire from the negative on the fan motor to the negative batterie terminal and the positive to the positive with the switch on the positive or how do i do it? please help!!!

 

You need the positive from the battery or another 12v source going through the switch to the fan and it can be grounded anywhere.

 

Why not just find an ignition "On" hot wire and tap directly into that. That way you have a fuse in the mix too and less chance of hurting something.

Good luck

I agree!!I like that switch idea with the ignition hot. Plus you won't forget and leave the fan on and kill the battery. I had a freind do that alot in his car. He also wasnt the brightest bulb either.....

 

Thats how I set up fans until I can afford the Pep Boys $35 dollar thermostat switch MUWAHAHAHAHA

Being poor sucks!

 

if that baby shorts out and catches fire it gona cost a bit more thatn 35 bucks to fix....at least put an inline fuse into your wire.

 

Yeah I said the above if you want to do it that way, but it is better to get acc. power from somewhere,

 

What I did on my old SVO before I sold it is run the + wire staight to the fan (with a fuse of corse) and made it a ground side switch so that when I turned on the switch it grounded the fan motor. That way you will not be burning up switches by having power going to them all of the time.
